Method for treating aviation aluminum wastewater with superhard 7075:

The wastewater discharged from the production of 7075 aviation aluminum exhaust contains some chemical elements and various aluminum salts. As aluminum salts are zwitterionic compounds, their forms change with the influence of acid, alkalinity, and other factors, which brings difficulties to their treatment. In general, in neutral, weakly acidic, and weakly alkaline media, the form of aluminum is mainly aluminum hydroxide and other insoluble and slightly soluble salts.

For the 7075 aviation aluminum wastewater, no matter what treatment method is used, it cannot decompose and destroy the heavy metals in it. It can only transfer the way it exists and its physical and chemical forms. The key is to adopt a reasonable process flow, scientific management and operation, reduce the amount of heavy metal 7075 aviation aluminum wastewater and its loss with the wastewater flow, minimize the amount of discharged wastewater, and reuse the treated wastewater. There are two general treatment methods: one is to transform the dissolved heavy metal 7075 aviation aluminum ions in the wastewater into insoluble heavy metal compounds, which are removed from the wastewater by precipitation and air flotation methods; Another approach is to concentrate and separate the heavy metal 7075 aviation aluminum in wastewater without changing its chemical form.
